EUGENE AT'WOOD, OF STONINGTON, CONNECTICUT SPINDLE FOR MACHINES FOR WINDING QUILLS.

SPECIFICATION forming part of Letters Patent No. 508,160, dated November 7, 1893. Application filed January 25, 1892- Serial No. 419,1(36. (No model.)

To aZZ whom it 11mg concern.-

Be it known that I, EUGENE A'IWOOD, of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Spindles for Machines for Winding Silk or other Thread on Quills, of which the following is aspecification, reference being bad to the accompanying drawings.

The class of spindle to which my improve.

ment relates is especially designed for winding silk or other thread on tapershuttle quills and is made hollow for the thread to pass through it and fitted externally with a traverse guide which rotating with it and traversing it longitudinally winds the thread with a regular 1 traverse upon the quill while the latter is held independently of the spindle in and a quill. Fig. 3 is a plan corresponding with Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

A is the spindle rail of a machine commonly known as the quiller.

B is the spindle bearing or bolster firmly secured in the said rail and bored cylindrically throughout to receive the lower part of a hollow spindle O. This spindle is made with a shoulder at aby which it is supported on the top of the bolster or bearing 13, and above this shoulder it is cylindrical externally nearly to the top where it is provided with a flange b to carry pins 0 upon which are loosely fitted the cones cl, which are placed thereon with their smaller ends upward the said pins being equi-distant from the axis of the spindle.

D is the sleeve of the traverse guide fitted to slide upon the cylindrical portion of the spindle 0 above the portion a. e is a light rod secured to the said sleeve and projecting upward through a recess f in the spindle flange b, and having at itsupper end an eye 9 which is situated opposite to one of the spaces betweenthe cones (Z and which is the guide by whichlthe thread is conducted to the quill E. This traverse guide has the nature of a flier. 'lo compel the said traverse guide to turn with the spindle while permitting it to move vertically or longitudinally thereon, a spline is fastened in the spindle and a longitudinal slot Z-qis made in the sleeve D to receive the said spline. On the opposite side of the spindle and sleeve a slot Z is provided in the spindle and a corresponding slot m is provided in the-sleeve for the passage of the thread from the interior of the spindle.

The quill E is fitted to the holder F which is so attached to an upright rod it that the axis of the quill is co-incident with the axis of the spindle and that the lower end of the quill may be received within the upper part of the spindle to which it is so loosely fitted that there is little or no friction. The rod h and the quill holder are or may be like those described in the Patent No. 381,011 before mentioned, the said rod being used to operate the stop motion as therein described. The said rod works freely through guides in a small standard '5 projecting upward from the flange of the bolster'B, the quill, the holder and the said rod being supported entirely by the cones which form aseat for the quill their taper being the reverse of the taper of the quill. To prevent the turning of the rod h it is provided with an arm 'n which runs on a fixed guide rod 0 secured to the standard The number of conesd represented is three, that number being generally sufficient, but it is obvious that a larger number or even two might be used.

I have not thought it necessary to represent the means of producing the traverse movement of the traverse guide, but as that forms no part of my invention it will be sufficient to say that the same means may be used for that purpose as are represented in th Patent N 0. 384,011, hereinloefore referred to.

In the operation the thread i supplied through the lower end of the spindle passes up through the spindle to the slot Z, outthrough the said slot and through the slot m in the sleeve D, thence upward to the guide G through which it passes directly to the quill.- The weight of the quill, quill holder and the rod h keepsthe quill or at least the silk that is wound upon it in contactwith the cones d which are caused to rotate freely upon the pins 0 as they are carried around the quills 5 bythe rotary movement of the spindle, and

as the silk is built upward upon the quill from the lower part by the rotation of the spindle, the 'quill is pressed upward and raised by the accumulation of the silk upon it. 10 -What I claim as my invention, and desire to secure by Letters Patent, is-

The combination with a rotary hollow-spin die andaquill holder longitudinally-movable I in line with said. spindle but independent thereof, of cones loosely mounted on said 15 forth.

EUGENE ATWCOD.
